3 1. Compliance with CE Marking 1.1. Abstract In Europe, EMC directive is enforced starting 1 st Jan. of 1996, and Low Voltage Directive starting 1 st Jan. of The display of CE mark that demonstrates that products imported to European Union conform to these directives is required. Inverter itself cannot function alone, but is de-signed as a component in order to control machines or equipment which includes that inverter installed in a cubicle. Therefore the conformance to EMC directive is not required on inverter it-self. But since the object of the Low Voltage directive is equipment that is designed to be used with rated voltage of 50 to 1,000 VAC or 75 to 1,500 VDC, CE should be marked on inverter as to the Low Voltage directive. But CE has to be marked on the final product installing inverters, that conforms to the EMC directive and the Low Voltage directive. And the product also may conform to Machine directive. The user that makes the final products have to take the responsibility for Marking of CE. For that reason, we recommend installation for Low Voltage directive and measurement for EMC directive, so that the products including our inverter should conform to the EMC and Low Voltage directive. TOSHIBA carried out Approval testing and confirmation testing on representative models under the circumstances based on installation and measurement so that our products should conform to each directive. But we cannot confirm the conformance of the user s products to the EMC directive. Since EMC environment changes according to the construction of the cubicle and the relation of other installed electric equipment and the condition of wiring and installation, please confirm the conformance to the EMC directive for the final products on your side

4 1.2. EMC directive An inverter itself is not an object of CE marking. A machine which consists of an inverter and a motor is an object of CE marking. The EMC directive includes the emission section and the immunity section. VF-nC1 can conform to EMC directive by means of installing the recommended EMI noise filter to the input side, and wiring properly. -> Emission: Emission of electromagnetic wave and electromagnetic interference -> Immunity: Resistance to electromagnetic interference [EMC directive] 89/336/EEC Table 1 Relative standard Noise type Test item Standard Applicable standards Emission Conducted Emission EN55011 Group 1 class A Radiated Emission EN55011 Group 1 class A Electrostatic Discharge IEC EN Radiated Electromagnetic field IEC Immunity Electrical Fast Transient/Burst IEC Surge Immunity IEC Conducted Disturbances IEC Voltage dips, short interruptions IEC and voltage variations - 3 -

5 1.3. Compliance with EMC directive The model, noise filter inside (1) Single-phase 200V class : VFNC1S-2002PL to 2022PL The above mentioned models install EMI noise filter inside. So the conducted and radiated noise can be reduced, optional EMI noise filters are not needed. (The additional noise filter should be installed, when more effective reduction is required.) (2) The main cables such as input to the EMI filter and output of the inverter and the signal cables should be shielded, then cable length should be wired as short as possible. The main input cable should be separated from the main output cable, and cables for control signal also should be separated from main cables, not wiring parallel and not bundling, cross the wires where necessary. (3) Install EMI filter and inverter on the same metal back plate in an inverter panel. The metal back plate or the cubicle must be grounded absolutely, by using short thick wires, separated from the main cables. (4) Shielded cables should be grounded on the metal back plate in order to reduce the radiated noise from the other cables. It is an effective measure that shielded cables are grounded close to the inverter or/and operation panel or/and EMI filter(less than 10cm). (5) Installation of the zero-phase and/or the ferrite core can also effectively reduce the radiated noise further.(input or/and output of inverter) - 4 -

7 1.3.2 The models without EMI filters (1) Shingle-phase 100V class : VFNC1-1001P to 1007P Three-phase 200V class : VFNC1-2001P to 2022P Shingle-phase 200V class : VFNC1S-2002P to 2022P This subsection explains what measures must be taken to satisfy the EMC directive. Insert a recommended EMI filter (Table 2) on the input side of the inverter to reduce radiation and transmission noises. In the combinations listed in Table 2, inverters were checked for conformity with the EMC directive. For inverters used in Japan, it is recommended to use the NF series of noise filters. Table 2 lists noise filters recommended for the inverters. Table 2.

The main input cable should be separated from the main output cable, and cables for control signal also should be separated from main cables, not wiring parallel and not bundling, cross the wires where necessary. (3) Install EMI filter and inverter on the same metal back plate in an inverter panel. The metal back plate or the cubicle must be grounded absolutely, by using short thick wires, separated from the main cables. (4) Please separate input cable to EMI filter from output cable as much as possible

8 (5) Shielded cables should be grounded on the metal back plate in order to reduce the radiated noise from the other cables. It is an effective measure that shielded cables are grounded close to the inverter or/and operation panel or/and EMI filter(less than 10cm). (6) Installation of the zero-phase and/or the ferrite core can also effectively reduce the radiated noise further. (Input or/and output of inverter) [Ex.

10 1.4. Low voltage directive Inverter itself is an object of the CE marking. The Low Voltage Directive defines the safety of the electric equipment. VF-A7 series conform to the Low Voltage directive based on EN Normative standard : EN50178/Electronic equipment for use in power installation Pollution degree :2( ) Over-voltage category : 3 200V class 3.0 mm ( ) EN50178 provides that for electronic equipment used in power installations. The main intention is to stipulate minimum requirements for the design and manufacture of electronic equipment, for protection against electric shock, for testing and for the integration into systems for power installations

11 1.5. Compliance with Low voltage directive E Please carry out the below mentioned countermeasures for the Low Voltage Directive in case of using VF-NC1 as components of your products. (1) Inverter should be installed in a panel. Pay attention to wiring openings, so that it should prevent someone from touching live parts through the opening in case of maintenance. 2) No more than 1 cable should be connected to one earth terminal of the main terminal board. In this case, other cables for ground should be grounded on the metal back plate and/or in the cubicle. The cross-sectional area of grounding cable shall be, in any case, not less than; Voltage class Single-phase 100V class Single-phase 200V class Three-phase 200V class Capacity of applicable motor (kw) Table 3.

12 2. Compliance with UL Standard and CSA Standard E The VF-NC1 models, that conform to the UL Standard and CSA Standard have the UL/CSA mark on the nameplate Compliance with Installation The VF-NC1 inverter must be installed in a panel, and used within the ambient temperature specification. They can be used at ambient temperature of up to 50 degrees by peeling off the label on the top of the inverter Compliance with Connection Use the UL conformed cables (Rating 75degrees or more) with the ring terminal at wiring to the inverter input/ output terminals (R/L1, S/L2, T/L3, U/T1, V/T2, W/T3) Compliance with Peripheral devices Use the UL listed fuses at connecting to power supply. Refer to the instruction manual about selecting the rating of them. Short circuit test is performed under the condition of the power supply short-circuit currents in below. These currents and fuse currents depend on the applicable motor capacities. Table 4.
